Fracture Dislocations of the Coccyx: A Case Series and Literature Review

Abstract

Study design: A case report and literature review. Objective: To present a rare case series of dislocation of the mid-coccygeal and sacro-coccygeal joints in a young adult and a baby, who were treated conservatively. Summary of background data: Dislocations of the mid-coccygeal or the sacro-coccygeal joints are infrequent injuries and are rarely reported. The treatment for these disorders is usually conservative. Methods: Detailed description of the posterior dislocation of the mid-coccygeal joint in a 19-year-old patient and a complete anterior dislocation (Salter-Harris type I) of the sacro-coccygeal joint in a 2 year and 8 months baby and management of both cases are presented, with review of the relevant literature. Results: A conservative treatment was performed in both cases. Clinical and radiological results at sixteen months after the injury in the first case, and five months in the second, revealed excellent results, with good healing of the dislocation and in normal alignment. Conclusion: Fracture dislocation of the mid-coccygeal and sacro-coccygeal joints in the young adults and pediatric population could be treated conservatively, as the potential of healing and remodelling is great. Closed reduction should not be attempted.
